"Microsoft has announced a new feature for Hotmail users that should help in the fight against email fraudsters and spammers.... Recipients of emails from clearly compromised accounts can now report them directly to Hotmail, as a new "My friendís been hacked!" reporting option has been added under the "Mark as" menu... [Moreover, ] Hotmail is also sharing these notifications with Gmail and Yahoo, which means that you could still be helping a hacked friend even if they don't also use Hotmail".
